I am trying to understand some things and hope you guys can offer some input.
I want to charge a standard 12v Lithium battery like a Chins or SOK in my truck. I want to keep the 12v amp draw to 10'ish amps or less. I am having a hard time finding a charger like this. Victron has one that will do 18 amps "charging" which I would assume would be close to 20 amps on the source 12v side but that is more charging load than I want.
I have found this which looks like it might (2/4/8 amp selector) work but I have some questions:
This charger does not have the "bulk/absorption" modes that a Victron or Renogy DC-to-DC charger would have. I do not quite understand the need for these modes with a Chins or SOK since the batteries built-in BMS is going to control all of this.
If I just left this Impulse 14.6v charger connected full time to the battery when I was driving or stopped, can I assume that the BMS in the battery will cut the charge load when the battery is full and then allow the charge to flow once the battery starts being discharged?
How does this work with a Victron/Renogy? I guess they know the battery is "full" when the BMS cuts the load and then they switch to a float mode of 13.6v?
I have looked for other 12v to 14.6 volt boost converters to basically do the same thing but there are not many of those out there either.
Any thoughts or ideas on how I can have a "charger" full time connected to a Chins/SOK and keep the amps in the 10'ish range would be greatly appreciated.
